FAQ
How does LORE identify rocks and minerals?
LORE identifies stones by analyzing a photograph you take or by using observable features you input, such as color and surface. It provides the closest matches from its 78-entry guide, along with confidence levels and physical tests for differentiation.
Can I use LORE offline?
Yes, LORE works entirely on your phone and can identify stones by features without an internet signal. This makes it a reliable tool for fieldwork where connectivity may be limited.
What kind of information does LORE provide about each stone?
Each entry includes details on how the stone forms, where it's found, its hardness on the Mohs scale, and its natural history. It also separates scientific information from folklore and traditional associations.
How does LORE handle privacy?
Your collection, notes, and settings remain on your phone. Photographs submitted for identification are resized, sent over an encrypted connection, and not stored. Anonymous analytics can be switched off.
What is LORE+?
LORE+ is an optional upgrade that provides unlimited identifications. The full guide, Explore, Stone of the Day, your collection, and Identify by Features remain free forever.
How often is LORE updated?
The latest version, 1.1, was last updated on October 17, 2026. Updates typically include improvements to the identification accuracy and expansion of the guide.
What is the age rating for LORE?
LORE is rated 4+ by the App Store, making it suitable for a wide range of users interested in learning about geology and minerals.
Is LORE suitable for appraising gemstones?
No, LORE is a field guide for identification and learning, not an appraisal tool. For valuation or safety concerns, it is recommended to consult a gemologist or a local geological society.
